There are so many horrible, horrible ideas in this article. If you look at schools in Finland, kids are in the classroom LESS. School hours are SHORTER. Studies have shown longer school days make kids less likely to learn.
Better options for after-school care would be fine, but that honestly isn’t schools responsibility. They are there to educate children, not provide babysitting services. If parent(s) can’t afford the after-school care, then they should re-think their work or living situation. Or consider the fact that they cannot afford children before they have them.
